Title: Falling prevention device for bridge
Inventor: NAKAMURA YUKIO
IPC: E01D19/04
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To actuate only compressive forces on a bridge girder and an abutment in an earthquake by providing both compressive spring characteristic and attenuating characteristic in a falling prevention device for a bridge. SOLUTION: An elastomer support 1 is compressed against the right and left swings of a bridge girder 11 in an earthquake and deformed outward like a bulge while fluidly deforming a damping material in the inside to attenuate the vibration of the bridge girder 11. Hence, the device restricts a large displacement exceeding the supporting length L of the girder and further, a tensile strength apt to bring breakage does not act on the abutment 12 of bridge girder 11 made of concrete owing to a falling prevention device S for the bridge but only a compressive force acts thereon. Hence, breakage is not easily brought about.  Since mutual girder bridges 11 or the girder bridge 11 and the abutment 12 are moved to abut against each other through the falling prevention device S in a small reaction from the initial vibration time in an earthquake. an effective falling prevention effect can be obtained without an extremely long supporting length L of the girder.

Title: Manufacture of wiring structure
Inventor: MOGAMI TOORU
IPC: H01L21/302
Filed: 1983-04-28
Abstract: PURPOSE:To form an insulating film flatly on a wiring without damaging the shape of the section of a wiring pattern with a steep side surface by executing a coating process and a flattening process for the insulating film through a high- frequency bias sputtering method in which bias voltage is changed over to two steps. CONSTITUTION:A silicon oxide film 704 is applied in thickness thicker than that of at least molybdenum wiring pattern through high-frequency bias sputtering under the conditions of comparatively small bias voltage. In this case, a form immediately after a patterning is kept as it is without a collapse in the form of the section of the molybdenum wiring pattern, and the tapered angle of the silicon oxide film 704b applied onto the molybdenum pattern considerably expands. However, the speed of application of the silicon oxide film on a flat surface is large as several hundred -1,000Angstrom /min, and the state can be realized for several min. High-frequency bias sputtering is executed to large bias voltage through which the deposition and etching of the silicon oxide film on the flat surface approximately balance. Inclined planes except the flat surface are all etched continuously under the conditions, and the tapered angles reach to approximately zero finally-that is, the silicon oxide film can be flattened approximately.

Title: Discharge lamp lighting device, equipment, and liquid-crystal display device
Inventor: NISHIMURA KIYOSHI
IPC: H05B41/24
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a liquid-crystal display device whose illuminating efficiency and uniformity ratio of illuminance are enhanced and in which the wear of the electrodes of a discharge lamp is suppressed. SOLUTION: When a negative pulse voltage is applied to a negative electrode 6b, electrons are emitted form the negative electrode 6b toward a positive electrode 6a, and a discharge directed from a bulb to the electrode 6b is decreased. Since the discharge between the electrodes and the bulb of the discharge lamp 6 or the like is also decreased, electrons are in a roughly uniform state over the whole discharge lamp 6. The luminance of the entire discharge lamp 6 can be held constant to enhance the uniformity ratio of illuminance. Because a work function is also made smaller, an initial discharge is facilitated and the lamp can be started easily.
